UNITED STATES ROLAND A. G S ELL, OF NEW YORK, N. Y.

CONVERTIBLE WATCH.

Application filcd May '22, 1923. Serial No. 6 10,71 1.

To all whom it may concern:

Be it known that I, ROLAND A. GsnLL, "a c iti Zen of the Republic of Switzerland, residing at New York, county of New York, and State oi New York, have invented certain new and useful Improvements in Convertible lVatches, of which the following is a specification.

The principal object of this invention is to provide a new and improved construction by means of which a miniature watch may be interchangeably and convertibly mountedupon any one of a plurality of supporting structures so that a single watch may serve as a ring watch, a wrist watch,

as a pendant from a necklace or any similar article of jewelry.

Another object is to provide the watch and supporting structures with cooperating detachable fastening means, which while permitting the watch to be readily detached will securely hold it upon the supporting structure in such a manner as to prevent the watch from becoming accidentally detached therefrom.

For the accomplishment of these and such further objects as will hereinafter be apparent to those skilled in the art to which this appertains, the invetnion consists in the construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawings, wherein is shown a preferred embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the claims hereunto appended.

In the drawings forming a portion of this specification Fig. 1 is a plan view of a watch attached to a ring in accordance with the principles of my invention.

Fig. 2 is a view showing the top of the ring type supporting structure and the back of the watch which has been detached therefrom.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a view similar to Fig. 3 showing the position of the parts as the watch is being attached to a supporting structure.

Fig. 5 is an inverted plan of the parts shown in Fig. l.

Fig. 6 is a perspective view of the watch attached to a wristband.

Fig. 7 is a plan view of the supporting structure used in connection with a wrist band.

Fig. 8 is a front elevation of the watch attached to a pendant supporting structure, and

Fig. 9 is a front view of the supporting structure shown in Fig. 8 after the watch has been detached therefrom.

As shown in the: drawings, the watch which is indicated generally by the numeral 10 has secured to the back thereof, a plurality of pins 11 which are adapted to be engaged within the keyhole slots 12, 12 in any desirable type of si'lpporting structure. 7) The supporting structure may be of the ring type which as shown in Figs. 1 to 5 inclusive, comprises the plate 18 and the ring shank or band 14. Figs. 6 and 7 illustrate a supporting structure for converting I" the watch 10 into a wrist watch and this structure comprises the plate 13 having at the ends thereof the ribbon attaching bands or loops 15, while in 8 and 9 the supporting structure comprises the plate 13 and a single ribbon band or loop 16.

As the stri-icture of each of the plates 13, 13 and 13 is identical, a descriptionof one will sufiice for all and the same reference characters are used to designate similar i153 parts of each. It will be noted by referring to Figs. 2, 7 and 9 of the drawing that three key-hole slots 1, 12 are preferably provided in each plate 13, 13 and 13 in the same relative position in each plate and as shown in Fig. 2 three pins 11 are provided upon the watch 10, the pins being secured to the watch in positions corresponding to the location of the slots 12, 12.

Each pin has an enlarged head 17 spaced or from the back of the watch so as to provide a neat sliding [it for the plate 13, between the enlarged heads 17 and the back of the watch. The plate 13 is provided with a pair of narrow slots 18 to provide a spring tongue 19 the free end of which extends across the enlarged part of the slot 12 and terminates just at the line of division between the enlarged and restricted portions of the slot.

When it is desired to secure the watch to the ring plate 13, the pins 11 are entered into the enlarged portions of the slots 12, 12*, it being understood that the enlarged portions of the slots are just of suflicient iflianieter to permit the ready passage oi the enlarged heads 17 of the pins 11 and that the restricted portions of the slots are of a Width just sutiicient to provide a neat fit for the pins 11. As the heads of the pins are inserted into the slots the spring tongue 19 will be pushed outwardly as shown in Fig. 4. The watch is then slid towards the right, as viewed in Figure 4, to move the pins into the restricted portions of the slots, which are of a length just sutlicient to permit the spring tongue to free end of spring below the head of the pin, occupying slot 12, the parts then being in the position shown in Fig. lVith the parts in this position it will be obvious that movement of the pins towards the enlarged portions of the slots is effectually prevented. When it is desired to detach the watch from any of the plates it is only necessary to insert an ordinary pin or other convenient sharp pointed instrument below the free end of the tongue 19 and to raise the tongue sufficiently to per mit the pins to be again moved to the enlarged parts of the slots.

lVhile I have shown the means for attaching the watch to the various structures in the form of pins and slots, it is to be understood that the construction shown is merely illustrative and is not to be considered as limiting the invention to the specific structure illustrated, as it will be obvious that the numerous modifications of the means for securing the watch which may be resorted to are practically unlimited. It will also be understood that the various forms of the supporting structures such as brooches, scarf pins, etc., may be used and that the shape and size of the watch may also be varied as desired. While the spring tongue 19 is shown as integral with the plate 13, it will be obvious that the tongue could be separate from the plate and riveted or otherwise secured thereto.

Having thus described .my invention, what I claim as new and desire to secure by Letters Patent of the United. States is 2-- 1. In a device of the class described, capable of being used as an article of jewelry and worn in any one of a. plurality oi? positions, the combination of a supporting plate having slots therein provided with restricted ends and also having an elongated recess provided with an enlargement near one end thereof, a watch having projections on the back thereof formed with heads capable of engagement in said slots and the enlargement in said recess, the shanks of said projections being movable in the restricted ends of said slots, and means extending longitudinally of said recess and engageable with the head of the projection mounted in the enlargement of said recess to prevent detachment o:t' the watch from said plate.

2. In a device of the class described, the combination of a watch having projections on its back and a supporting plate provided with slots for receiving said projections and with an elongated recess provided with an enlargement near the end of said recess, and a resilient tongue within said recess having its free end terminating at the enlarged portion of said recess, and engageable with one of the projections on the back of said watch to prevent detachment of the watch from said plate.

In testimony whereof I have aliixed my signature.

ROLAND A. GSELL.
